This research finds that, compared to a future power system more heavily dependent on gas, large-scale investment in offshore wind would impact positively on UK GDP and employment. GDP increases by 0.8% by 2030 and there are over 100,000 additional jobs by 2025, falling to 70,000 additional jobs by 2030. The development of offshore wind capacity would stimulate construction and manufacturing demand over the period to 2030. In the longer term, it would prevent locking the UK into natural gas usage and imports.
